I have been using Ubuntu for quite some time now. At first everything worked good. After some update that was released lately (probably less than 2 months), terminal does not autocomplete commands any more.
When I try to type something and try to autocomplete it with tab... it just does nothing.
I tried to look at some solutions on this site including this
Terminal autocomplete doesn't work properly
But that did not work. I tried to reinstall Ubuntu, both 20.04.2.0 and 21.04, but the problem persists.
Before when I used the autocomplete function by pressing the tab key, I could hear a beep from the PC, but I do not hear the beep anymore.
Any help please??
